基于嵌入式Linux串行通信GUI终端设计及实现

The design and implement of the serial port GUI terminal based on embedded Linux

Linux作为开放源代码的操作系统,以其内核精简、功能可裁剪、高稳定、高性能、多用户、多任务等优势,在嵌入式领域得到广泛应用。ARM9嵌入式平台大多采用图形界面Linux操作系统,实现应用开发,必须适应开发板图形界面、操作系统、硬件平台三方面的要求。本文讨论基于ARM9平台、Linux2.6内核、QT/E环境的通信终端程序设计,简要介绍了ARM9嵌入式图形界面开发环境、开发步骤,详细介绍了串口通信程序的设计与C++实现。

As an open source operation system,Linux is widely used in embedded system for it＇ s advantage of tidy kernel, cropped function, high stability, multi-user, multitasking. The Linux operation system is adopted inmost ARM9 platform.Developing the application software must accommodate the UI,the OS and the hardware.This paper discusses the design of the ComTcrminal based on ARM9.Linux2.6 and QT/E, introduces the UI developing environment and procedure briefly, present the design and C＋＋ implement of the ComTerminal thoroughly.
